I have listened to mine with the Zu WAX, Libtec, and Ibis. I enjoyed them with all, but there is a definite improvement in performance as you move up from the different levels.
Keep an eye out on ebay, Zu regularly has the Wax cables for auction. If you want the others, you have to purchase directly from Zu, or buy used.
There is a pair of used Ibis for sale here on Agon for $550. IMHO This would be a great upgrade.
